Based on the definition of the C union .below, answer the following questions Write the declaration of port_d and .1 .tris_d to work as PORTD and TRISD Use the BT8 in the union below to .2 initialize the direction (input/output) as .shown in the union below If PB1 is low, turn on the Buzzer. Do .3 .not use BT8 field. No debouncing Toggle all relays by using the relays .4 field and the correct logical operations. Do .not use BT8 field typedef union { unsigned char BT8; struct { } unsigned LEDs :3; unsigned PB1 :1; unsigned PB2 :1; unsigned Relays :2; unsigned Buzzer :1; >UBvte: * (14 ) //define the field BT8 to use it as a byte here //structure of 3 Leds, PB1, PB2, 2 Relays, Buzzer //field Leds as one field for 3 LEDs //field PB1 (one Push button) //field PB2 (one Push button) //field Relays (2 relays as one field) //field Buzzer (output, one bit)
